MONROE HUDGENS, OF OCONNERS, TENNESSEE.

LOADER AND UNLOADER.

Specification of Letters Patent.

Patented May 22, 1906.

Application filed December 28, 1905. Serial No. 293,588.

To all whom it may concern.-

Be it known that I, MONROE HUDGENS, a citizen of the United States, residing at OConners, in the county of White and State of Tennessee, have invented a new and useful Loader and Unloader; and I do hereby declare the following to be a full, clear, and we act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to grain-carrier boxes adapted to unload and load wagonsthat is to say, after the wagon has been backed up in proper position adjacent to the granary the carrier box may be lowered over the wagon and after the carrier-box is filled then hoisted to the proper height to allow the same to be swung into the granary.

This invention may be used for loading and unloading straw or any other light commodity, and more particularly the invention comprises a device having a hinged bottom which is provided with an automatic locking and catch device, which will be hereinafter more particularly set forth.

This invention comprises further objects and combinations of elements, which will be hereinafter more fully described and shown in the accompanying drawings, and the novel features thereof will be particularly pointed out by the appended claims.

To obtain a full and correct understanding of the details of construction and combination of features, elements, and advantages, reference is to be had to the hereinafter set forth description in connection with the accompanying drawings, wherein Figure 1 is a perspective view of the carrier-boX, being attached to a suitable carrier, which hangs from the upper part of the granary; Fig. 2, an enlarged perspective view of the carrier-box, and Fig. 3 a longitudinal section through the automatic locking and catch device.

Making renewed reference to the accompanying drawings, wherein similar reference characters indicate the corresponding parts in the several illustrations by figures, 1 designates a rectangular-shaped carrier-box, having a suitable bottom 2, which is suitably hinged, as at 3, which will allow the same to swing downward when the automatic locking and catch device is operated. Upon each side of the bottom 2 are a pair of projecting arms 4, which extend adjacent to the side of carrier-box, the ends of the arms being suitably connected to the ends of springs'5, the other ends of which are secured, as at 6, to the side of the carrier-box. These springs are for the purpose of restoring the bottom to its normal position after the commodity has been dumped.

7 designates spring catches, comprising strips of metal bent upon themselves, as at 8, forming arms 9 and 10 at right angles to each other, the arms 9 being secured to the under face of the bottom, as at 11, and the arms 10 being provided with catches 12, which are riveted, as shown at 13, forming shoulders 14, which shoulders are adapted to engage shouldered strips 15, which are bolted or otherwise secured to the face of the carrier- 'boX, as shown clearly in Fig. 2 of the accompanying drawings.

Projecting from the face of the carrier-box are arches 16, which bridge the arms 10 when the catches are closed. Mounted between arms of said arches are cammed levers 17, which are eccentrically mounted therein. These levers are adapted to. act u on the face of the arms 10 to securely hold t e shoulders 14 upon the arms 10 in engagement with the shouldered strips 15, as shown clearly in the drawings. To provide further means for holding. the cammed levers in engagement with the faces of the arms 10, suitable springs 18 are provided, the ends of which are secured, as at 19, to the arms of the cammed levers and the other ends being securely attached, as at 20, to the face of the carrier-box, as clearly shown in the drawings.

Attached to each arm of the cammed levers 17 is a suitable rope or cable a, said rope or cable having its middle portion thereof attached to another rope or cable, which is designated in the drawings by the letter 0, said rope or cable being adapted to pass between arms d, projecting from the face of the carrier-box, and to also engage with an antifrictional roller e, which is mounted u on a suitable pin f, which is carried by sai projecting arms. Said rope or cable a is adapted to pass down to a suitable location to allow the pressure to be applied thereto.

Projecting across the upper part of the carrier-box is an arch g, having a suitable swiveled loop h, which is adapted to have connected thereto a hook is, which is integral with a pulley m, which is carried by a rope or cable n of the usual carrier mounted to travel upon a suitable track-beam, as shown; but in the present invention the said carrier and track-beam forms no part of the invention only in combination with the carrier-box.

From the foregoing it will be plainly observed that a very eflicient device for unloading and loading grain or other like commodities from wagons to a barn or granary is provided which may be manufactured comparatively cheap andcsold to the trade at a very slight cost.

Having thus fully described the invention, what is claimed as new, and desired to secure by Letters Patent, is

1. A device of the character described, comprising a rectangular boxing, a hinged bottom therefor, lock and catch devices for said bottom, comprising metallic strips, a shoulder carried by each strip, adapted to engage a similar shoulder secured to the face of the boxing, cammed levers to securely hold the shoulders in locked relation to one another, and means for holding the cammed 1 face of the boxing, cammed levers to cooperate with said strips, springs to restore the cammed levers to their normal positions, a cable connected to the arms of said levers, pulleys for said cable, and means for raising and lowering the boxing.

3. A device of the character described, comprising a rectangular boxing, a hinged bottom therefor, 'means for restoring said bottom to its normal position, lock and catch devices comprising metallic strips, a shoulder carried by each of said strips to engage a shouldered strip secured to the face of the MONROE HUDGENS.
